Mike Smith 595bd0d58e Lightly overhaul the memory sizing code again. ... - The kernel environment variable 'hw.physmem' can be used to set the amount of physical memory space, based at 0, that FreeBSD will use. Any memory detected over this limit is ignored. Documentation for this is available under 'help set tunables' in the loader. - In the case where system memory size can't be accurately determined, hw.physmem is used as a best-guess memory size, but speculative probing will be used to determine actual memory size if any of the guesses or hints are 16M or more. - If RB_VERBOSE, we list the memory regions as we test them. - The compile-time option MAXMEM supplies a default value for 'hw.physmem'.		1999-07-02 20:33:32 +00:00
